BALL-BEARING.

SPECIFICATION forming part Of Letters Patent N0. 401,748, dated April 23, 1889.

Application tiled December 1'7, 1888. Serial No. 293,873. (No model.)

To @ZZ whom, t may eoncrn:

Be it known that I, HERMANN KUNATH, a suhjeet ot the King oli' Saxony, and residing at Dresden, in the Kingdom ot' Saxony, German Empire, have invented certain .new and useful Imprtwements in Adjustable Balldearings Vl'or Carriage-Axles, of which the following is a i'ull and clear description.

My invention relaties to adjustable ball-bearings tor carriage-axles, and has lforits purpose that the axle-box mayv he removed from the spindle without the halls falling out, and that the cone hv which the balls are regulated is prevented lrom accidentallytightening on the halls and preventing them revolving.

in order to make my invention more clear, I refer to the accompanying sheet of drawings, in whieh similar letters denote similar parts throughout the different rfigures.

Figure l is a longitudinal section of in v improved axle-hon. Fig. 2 is a eross-seet-ion through the line f1: y, Fig. l. Fig. 3 is a view showing, on a larger scale, the hearing of the halls and the rings tor holding them in their platee when the ho.\Y is removed l'rom the end of the axle-spindle. Fig. t shows a side view ol' the manner in which the regulating-cone is held tast. Fig. 5 is an end view ot Fig. i.

A is the spindle, which is screwed at its outer end and has a I utling-ring, S, at the inner end. The huttinge-ing S is provided with an oil-hole, s.

B is the axle-hor, on which the carriagewheel is tastened. The axle-spindle A is Iitted with the @one t" at the trout, which is screwed on, and at the hack side with the cone e, which alntts against the lntttifing-ring S,and is prevented trom turning hv the pin In the liox yll are fitted the rings e e at the l'ront and haelt side and held in their proper positions hv the rings n1` nl. The rings e e are so Aformed that the)Y eneirele the halls d to a certain extent, as mayv he seen hv relerence to Fig. f3. rlhe rings e, whieh Carry the halls d, are made vfrom hard steel, while the rings e', which hold the halls d in the rings e, are made trom wrought-iron. 'ihe rings hold the halls in such a manner that when the axle-inox is removed from the axle-spindle the halls cannot tall out. lhe inner end ot the aule-spindle is provided with a inlnieatinggroove, s', and the hinting-ring S with the oil-hole s, which is closed by the screw "e, The groove s extends to the inside ot the axlebox l. Between the hutting-ring S and the ball-rings e e are titted leather washers i i", which shut the axle-box completely at the hack side.

The adjustment and fastening otl the outside cone, e, are as follows: rlhe cone o is screwed onto the front part of the axle-spindle A. The end of the spindle is tiattened on one side, as seen in Figs. 4 and 5, and a washer, f, fitted over the same. This washer fis made from some soft metal, as brass or bronze. The washer f `is prevented lroln turning by the tlat on the end of the spindle, and. is pressed against the serrated end ot' the eone e', In front of the washer f is a locknut, g, screwed on the end ot the spindle, whieh presses the sott washer j' against the serrated end ot the eone e and prevents the saine vfrom accidentally turning. The spindie A is titited with a linehpin, 71, in front of the lock-nut g, in order to prevent the nut `f/ trom coming ott'. The end ol the spindle is protected hv the eap 7i, which screws into the axle-box ll.

rlhe hearings may he easily adj usted hy removing the eap and looseningthe nut g and washer j', when. the cone may he adjusted at pleasure bv a wreneh, (the end ot' the cono is provided with squares for this pnrpose,) and the washerfainl nut f/ again tightened up.

Having described my invention, what l desire to elaim and protect h v Letters Patent in the United States isl. ln adjust-able hall-hearings tor carriageaxles, the ('onihination ot the rings e e e e, cones e r', axle-spindle A, washer j', loellwnut (j, and box i3, with eap r, suhstantiall)Y and tor the purpose as deserihed.

i?. In adjustable hall-hearings t'or carriageaxles, the eonihimltion ot the spindle A, hutting-ring S, ones e f", rings e e e e', leather washers 17, sott-metal washer f, lock-nut g, balls d, axle-box ll, and cap L', substantiallyY and For the purpose as described.

ln witness whereot' l have hereunto set my hand in presence otl two witnesses.
